The flexible through-connection process, operational in a Mobile Switch Center, that provides support for allowing the call routing processor of the Mobile Switch Center to independently perform a through-connection/switch-connection based on different types of calls so that the Mobile Switch Center can make a through-connection at different stages of the outgoing call leg. In operation, the present flexible through-connection process includes in the call control processor of the switching system a new parameter in the existing inter-process message which is sent to the call routing processor at call setup time. The values supported for this new parameter will be pre-defined in the Mobile Switch Center and used by the call routing processor to determine when to perform through-connection/switch-connection for an outgoing call leg. When the call routing processor routs the call out and the outgoing call is at the stage, in which the value of the parameter received is defined for, it performs a through-connection operation. Additionally this flexible through-connection process automatically disconnects the other call leg, i.e., switches the connection from one called leg to another called leg when multiple call legs are involved for an incoming call.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A flexible through-connection process, operational in a Mobile Switch Center that contains a call control processor and a call routing processor, for making a through-connection to a destination at different stages of the call connection, comprising: means, responsive to receipt of an incoming call at a Mobile Switch Center, for determining whether a called mobile subscriber station identified in said incoming call is provisioned to receive services from an external server for said incoming call, comprising: means for transmitting a query to a Home Location Register of said Mobile Switch Center requesting pre-provisioned information of said called mobile subscriber station; and means, responsive to said incoming call being provisioned to receive services from an external server, for transmitting data at call setup time from said call control processor to said call routing processor indicative of a set of conditions under which said call routing processor, independent of said call control processor, performs a through-connection to said called mobile subscriber station and a set of conditions under which said call routing processor, independent of said call control processor performs a through connection to said external server followed by a switch connection to one of said called mobile subscriber station and an alternate destination pursuant to satisfaction of one of said set of conditions during the processing of said incoming call, comprising: means, responsive to receipt of pre-provisioned information of said called mobile subscriber station indicative of said called mobile subscriber station being provisioned to receive services from an external server, for transmitting data from said call control processor to said call routing processor requesting said call routing processor to establish a call connection to said external server, and means for setting a through-connection indicator in said transmitted data to indicate a one of a through-connection and a switch-connection to be implemented during the processing of said incoming call upon occurrence of an associated condition.
2. The flexible through-connection process of claim 1 , further comprising: means, located in said call routing processor and responsive to said transmitted data, for extending said incoming call connection from said calling subscriber station to said external server.
3. The flexible through-connection process of claim 2 , further comprising: means, located in said call routing processor and responsive to said transmitted data and occurrence of said associated condition, for implementing a one of a through-connection and a switch-connection identified in said transmitted data to redirect said incoming call to an alternate destination.
4. The flexible through-connection process of claim 3 wherein said means for implementing is responsive to a one of said associated conditions, including: Initial Address Message (IAM) sent, Address Complete Message received, call answered, call is being forwarded, a seizure signal sent.
5. The flexible through-connection process of claim 3 , further comprising: means, located in said call routing processor and responsive to said transmitted data and occurrence of said associated condition, for automatically disconnecting said extended call connection to said external processor.
6. A flexible through-connection process, operational in a Mobile Switch Center that contains a call control processor and a call routing processor, for making a through-connection to a destination at different stages of the call connection, comprising: determining, in response to receipt of an incoming call at a Mobile Switch Center, whether a called mobile subscriber station identified in said incoming call is provisioned to receive services from an external server for said incoming call, comprising: transmitting a query to a Home Location Register of said Mobile Switch Center requesting pre-provisioned information of said called mobile subscriber station; and transmitting, in response to said incoming call being provisioned to receive services from an external server, data at call setup time from said call control processor to said call routing processor indicative of a set of conditions under which said call routing processor, independent of said call control processor, performs a through-connection and a set of conditions under which said call routing processor, independent of said call control processor performs a through-connection and a set of conditions under which said call routing processor, independent of said call control processor performs a switch-connection to said external server and said destination during the processing of said incoming call, comprising: transmitting, in response to receipt of pre-provisioned information of said called mobile subscriber station indicative of said called mobile subscriber station being provisioned to receive services from an external server, data from said call control processor to said call routing processor requesting said call routing processor to establish a call connection to said external server, and setting a through-connection indicator in said transmitted data to indicate a one of a through-connection and a switch-connection to be implemented during the processing of said incoming call upon occurrence of an associated condition.
7. The flexible through-connection process of claim 1 , further comprising: extending, in response to said transmitted data, said incoming call connection from said calling subscriber station to said external server.
8. The flexible through-connection process of claim 7 , further comprising: implementing, in response to said transmitted data and occurrence of said associated condition, a one of a through-connection and a switch-connection identified in said transmitted data to redirect said incoming call to an alternate destination.
9. The flexible through-connection process of claim 8 wherein said step of implementing is responsive to a one of said associated conditions, including: Initial Address Message (IAM) sent, Address Complete Message received, call answered, call is being forwarded, a seizure signal sent.
10. The flexible through-connection process of claim 8 , further comprising: automatically disconnecting, in response to said transmitted data and occurrence of said associated condition, said extended call connection to said external processor.
